People with this syndrome may be on one side of the face feel less (pain and temperature) and on the other side of their body too. The Horner's syndrome is seen in this syndrome: a drooping eyelid and a pupil is smaller. It depends on the location if half-sided sweat secretion is reduced (sometimes even more!) Sensory disturbance in the soft palate. The characteristic features are: suffer from hiccups, acute vertigo, jerky eye movements (nystagmus), difficulty swallowing, vomiting, and disorder in the vocalisation, including dysarthria and hoarseness. Wallenberg syndrome (Lateral medullary syndrome)Ĭerebral infarction or hemorrhage (stroke) in the medulla in the brainstem, has been named specifically as the syndrome of Wallenberg (or Wallenberg syndrome). In other states with loss of consciousness such as coma, the brain still works.Īn infarct in the brain stem is given a name that is dependent on the area in the brain stem: Syndrome of Benedict, Claude, Foville, Millard-Gubler, Wallenberg and Weber. When a person's brain stops functioning, this state is called brain death. Like the frontal and temporal lobes, the brain stem is located in an area near bony protrusions making it vulnerable to damage during an accident. All information to and from the body passes through the brain stem on its way to or from the brains.
The brain stem plays a vital role in attention, arousal, and consciousness. Scattered throughout the brainstem, is the reticular formation that controls consciousness (that distinguishes important and unimportant stimuli)ĭiminished vital capacity in the respiration, which is important for speechĭifficulty in swallowing food and water (Dysphagia)Īll of the vital functions mentioned above can be damaged and can give a direct life threatening danger. It affects alertness, tasting, formation of saliva, vomiting, urination, ability to sleep (sleep-wake cycle regulation), sense of balance (vestibular), feeling of gravity and can cause a central sleep apnea (CSAS), The brainstem monitors and regulates the autonomic nervous system breathing, heart rate, blood pressure and circulation, chewing and swallowing, reflexes of seeing and hearing (startle) sweating, digestion, body temperature, pupil size. The hypothalamus and pituitary gland also belong to the brainstem. It consists of the medulla oblongata, the pons and the midbrain, (mesencephalon). The brain stem serves as a connection between the brain and the body, coordinating motor control signals sent from the cerebrum to the spinal cord. The brain stem (truncus cerebri) is located deep in the brains and provides the connection with the spinal cord. This side is under construction, our apologies for this inconvenience
